Comparing Different Text Similarity Methods
Bao, J.; Lyon, C.; Lane, P.C.R.; Ji, W.; Malcolm, J. (University of Hertfordshire, 2007)This paper reports experiments on a corpus of news articles from the Financial Times, comparing different text similarity models. First the Ferret system using a method based solely on lexical similarities is used, then ... -
A Constructivist Approach to Robot Language Learning via Simulated Babbling and Holophrase Extraction
Saunders, J.; Lyon, C.; Foerster, Frank; Nehaniv, C.L.; Dautenhahn, K. (Institute of Electrical and Electronics Engineers (IEEE), 2009)It is thought that meaning may be grounded in early childhood language learning via the physical and social interaction of the infant with those around him or her, and that the capacity to use words, phrases and their ... -
Copy detection in Chinese documents using Ferret
Bao, J.; Lyon, C.; Lane, P.C.R. (2006) -
Copy detection in Chinese documents using the Ferret: a report on experiments
Bao, J.; Lyon, C.; Lane, P.C.R.; Ji, W.; Malcolm, J. (University of Hertfordshire, 2006)The Ferret copy detector has been used for some years on English texts to find plagiarism in large collections of students coursework. This article--reports on extending its application to Chinese, which differs from English ... -
Detecting Short Passages of Similar Text in Large Document Collections
Lyon, C.; Malcolm, J.; Dickerson, B. (2001) -
Elman's model of natural language acquisition
Lyon, C. (University of Hertfordshire, 1993)Elman first aims to give an account of natural language showing how a connectionist system can model its significant features. Using the same network he then goes on to model the acquisition of language by children. This ... -
Entropy Indicators for Investigating Early Language Processes
Lyon, C.; Nehaniv, C.L.; Dickerson, B. (The Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB), 2005)We examine evidence for the hypothesis that language could have passed through a stage when words were combined in structured linear segments and these linear segments could later have become the building blocks for a full ... -
Evaluating parsing schemes with entropy indicators
Lyon, C. (University of Hertfordshire, 1997)This paper introduces an objective metric for assessing the effectiveness of a parsing scheme. Information theoretic indicators can be used to show whether a given scheme captures some of the structure of natural language ... -
Evaluating Parsing Schemes with Entropy Indicators.
Lyon, C.; Brown, S. (The Association for Mathematics of Language, 1997)This paper introduces an objective metric for evaluating a parsing scheme. It is based on Shannon's original work with letter sequences, which can be extended to part-of-speech tag sequences. It is shown that this regular ... -
Evolution of language structure : survival of the fittest in a statistical environment
Lyon, C. (University of Hertfordshire, 1998)The structure and other characteristics of natural language can be illuminated by an investigation into the real world conditions within which language functions. Language is taken as a medium in which messages are produced, ... -
Experiments in Electronic Plagiarism Detection
Lyon, C.; Barrett, R.; Malcolm, J. (University of Hertfordshire, 2003)This report first describes three plagiarism detection systems: the Ferret, developed here at the University of Hertfordshire, (Section 2), Turnitin (Section 3) and CopyCatch (Section 4). The Ferret is a stand-alone system ... -
Exploiting statistical characteristics of word sequences for the efficient coding of speech.
Lyon, C.; Dickerson, R. (Chinese Information Processing Society of China, 1999)Characteristics of natural language can be illuminated through the application of well known tools in Information Theory. This paper shows how some of these characteristics can be exploited in the development of automated ... -
A fast partial parse of natural language sentences using a connectionist method
Lyon, C.; Dickerson, R. (Morgan Kaufmann Publishers Inc., 1995)The pattern matching capabilities of neural networks can be used to locate syntactic constituents of natural language. This paper describes a fully automated--hybrid system, using neural nets operating within a grammatic ... -
From babbling towards first words : The emergence of speech in a robot in real-time interaction
Rothwell, A.; Lyon, C.; Nehaniv, C.L.; Saunders, J. (Institute of Electrical and Electronics Engineers (IEEE), 2011)This paper describes a system that simulates word form acquisition without meaning as a preliminary stage in language acquisition, through interaction with a human teacher. The system extracts phonemes from the teacher's ... -
Homophony and Disambiguation Through Sequential Processes in the Evolution of Language
Lyon, C.; Nehaniv, C.L.; Baillie, J.; Warren, S. (2007) -
Incremental Retrieval of documents relevant to a topic
Lyon, C.; Malcolm, J.; Dickerson, R. (2002) -
Neural nets for a language processing task: tag disambiguation
Lyon, C. (University of Hertfordshire, 1992)This paper first shows how part-of-speech tags cen be ambiguous and why it is necessary to disambiguate them. Prototypes which can do this are developed in a limited natural language domain. The representation of syntactic ... -
Plagiarism is easy, but also easy to detect
Lyon, C.; Barrett, R.; Malcolm, J. (2006-01) -
Reducing the Complexity of Parsing by a Method of Decomposition.
Lyon, C.; Dickerson, R. (Association of Computational Linguistics, 1997)The complexity of parsing English sentences can be reduced by decomposing the problem into three subtasks. Declarative sentences can almost always be segmented into three concatenated sections: pre-subject, subject, ... -
The Segmentation of Speech and its Implications for the Emergence of Language Structure
Lyon, C.; Dickerson, R.; Nehaniv, C.L. (2003)This paper reports a phenomenon supporting the hypothesis that the emergence of structure in the evolution of language was a staged process. To develop a grammatical structure it seems necessary to first have discrete ...
